Your Baby at 3 Months Old

Month To Month Baby Development


By month three, you are starting to create a solid routine with your baby. You may notice your baby's personality starting to emerge. Your child responds to your voice by verbalizing, and begins to play with the objects in her world.

Baby Development Milestones To Watch For

  • Baby should now be able to lift his head and chest off the floor during tummy time.

  • Baby finds his hands. You will notice your child watching and beginning to play with his fingers.

  • Baby is verbally responding to you! You will begin to hear laughing, cooing, and babbling in response to your voice.

  • Baby becomes more aware of his or her surroundings. Your infant will start to intentionally grab at objects and wave them around.

How To Help Your Baby

  • Stimulate your baby's senses. Give your child toys that are easy to grab and shake. You can also attach a stuffed animal or other noise-making toy to their stroller or car-seat. Wrist rattles are also a favorite at this age. A baby, at 3 months old, loves anything she can grab, shake, or drop.

  • Put your baby in a bouncy seat. This allows her to sit more upright and see more of what's happening around her.

  • Sing and talk to your baby as much as possible. You will strengthen your bond with your baby, while helping him to develop focus and listening skills.

  • Keep up with the tummy time! You should be doing this with your baby daily, working up to 15 or 20 minutes each day. It's important to continue developing muscle control of the neck and upper body, as well as preparing for upcoming motor skills, such as rolling over, sitting, crawling, and eventually walking.

Common Concerns - Sleep

It's easy to worry when you are convinced your baby will never sleep through the night. Most babies at this age sleep about 15 hours each day. However, no two babies are alike. Some may already be sleeping through the night, while others prefer to sleep during the day, waking often at night. It will help if you encourage your baby to stay awake longer during the day by incorporating plenty of activities into your daily routine. It may also help to create a sleep routine during your day, working them toward 2 or 3 shorter daily naps, encouraging a longer stretch of sleep overnight.

New Parent Help: "What do I do when my baby doesn't like tummy time?"

You are not alone! Many babies do not like tummy time, but it is an important part of helping babies build strength. In this situation, regular practice is key. Start with short tummy time sessions, making them longer as your baby begins to get the hang of things. It also helps to work on tummy time during points in the day when your baby is happiest. A three month old baby is starting to become more aware of her surroundings, so giving a baby on her belly something interesting to focus on is helpful, even her own reflection! Don't be afraid to get down on the floor with your infant. Also, remember that tummy time activities don't always have to take place on the floor. You can also build muscle strength with your infant on your chest or lap, which may make tummy time a more enjoyable experience for everyone.
